聚乳酸纖維（PLA）
生產原料乳酸是從玉米淀粉制得，故也稱為玉米纖維，PLA纖維是在美國**的谷物公司Cargill公司研制成功的玉米聚乳酸樹脂的基礎上，在1997年該公司和美國Dow Polymers公司合股成立了 Cargill Dow Polymers公司，全力發展了聚乳酸原料，到2002年聚乳酸年產已達14萬噸，生產的PLA纖維商品名為Ingeo。日本鐘紡、尤尼契卡和可樂麗公司生產的PLA纖維商品分別為Lactron、Terramac和 Plastarch，美國杜邦公司和孟山都等公司也開始開發PLA纖維。目前，商業化生產的PLA纖維是以玉米淀粉發酵制成乳酸，經脫水聚合反應制得聚乳酸酯溶液進行紡絲加工而成。PLA纖維之所以受到眾多纖維公司和消費者關注，并顯示強大的生命力。淄博蛋白纖維紡織品科技開發有限公司，將永遠致力于各種聚乳酸玉米纖維等天然纖維各種紡織品的開發、生產，以高品質的天然纖維紡織品服務全人類。主要PLA纖維有許多突出的優點：
（1）原料來自于天然植物，容易生物降解，降解產物是乳酸、二氧化碳和水，是新一代環保型可降解聚酯纖維。
（2）有較好的親水性、毛細管效應和水的擴散性；
（3）模量和彎曲剛度是滌綸一半，故手感柔軟；
（4）有良好的回彈性、抗皺性和保形性；
（5）限氧指數較高（L0I 24-29），點燃后自熄性好、燃燒發煙量低，有較好阻燃性；
（6）有防紫外線能力，紫外線吸收率低；
（7）折射率低、染色制品顯色性好；
（8）易染性，染色溫度低于滌綸。
Corn polylactic acid (PLA) fiber
Raw material lactic acid from corn starch system, therefore, also known as the corn fiber, PLA fiber is in the famous American grain company Cargill company successfully developed corn on the basis of polylactic acid resin, in 1997 the company and the United States, the Dow Polymers partnership established Cargill Dow Polymers company, to the development of polylactic acid raw materials, to 2002 with an annual production capacity of polylactic acid has reached 140000 tons, the production of PLA fiber goods Ingeo called. Japan clock spinning, especially the cheka and coke li company produces the PLA fiber goods Lactron respectively, Terramac and Plastarch, the United States dupont and biotechnology companies are also beginning to tap such as PLA fiber. At present, the commercial production of PLA fiber is made from corn starch fermentation lactic acid, the dehydration polymerization reaction system polylactic acid ester solution spinning processing and become. The PLA fiber by numerous fiber companies and consumers attention, and shows strong vitality. Zibo protein fiber textile technology development co., LTD., will always be committed to all kinds of corn polylactic acid fiber textile products development, production, by the high quality natural fiber textiles service all mankind. Main PLA fiber has many outstanding advantages:
(1) raw materials from natural plants, easy to biological degradation, degradation product is lactic acid, carbon dioxide and water, is a new generation of environmental protection biodegradable polyester fiber.
(2) has good hydrophilicity, capillary effect and water diffusivity;
(3) modulus and bending rigidity is polyester half, so soft,
(4) have good resilience, wrinkle resistance and conformality;
(5) the limit oxygen index is higher (L0I 24-29), lit self-extinguishing, combustion smoke volume is low, have a good flame retardancy,
(6) have ultraviolet prevention ability, uv absorption rate is low;
(7) refractive index is low, the dyeing products good color rendering,
(8) tingible sex, dyeing temperature lower than polyester.
